House Extensions in Enfield.
An extension is the surest way to get the open-plan kitchen and dining room most families want, and the houses in Enfield generally lend themselves to it: a side return to fill, a rear garden to build into, or on larger plots room for a full-width or double-storey addition.
We design the extension around how you will use it, not around the maximum footprint the rules allow. That means thinking about light, the level change to the garden, where the kitchen sits, how the old and new parts of the house meet and what happens to the rooms you already have. The structural engineering, party wall matters and building control inspections are all handled by us.
Approvals are checked on the first visit. Many single-storey rear extensions fall within permitted development, but the London Borough of Enfield applies tighter rules in conservation areas and to flats and listed buildings, so we confirm the route before any drawings are produced and then manage the application if one is needed.

Enfield: the houses and the planning rules.
Enfield is a market town on the northern edge of London with a wide mix of housing: Victorian terraces near the stations, Edwardian semis on the avenues, 1930s houses across much of the borough and larger properties towards Forty Hill and the green belt. The town centre and Forty Hill are conservation areas.
We designed, supplied and fitted a white high-gloss kitchen with a 50 mm black granite worktop and Neff appliances on Lea Street, and the borough's family houses are well suited to extensions, lofts and full refurbishments.
The Enfield Town, Forty Hill and Clay Hill conservation areas cover the historic centre; most other streets are unrestricted.
London Borough of Enfield
Enfield decides applications. Most streets outside the conservation areas have full permitted development rights.
Terraces
Side-return and rear extensions on the Victorian terraces near Enfield Town usually engage the Party Wall Act; we serve notices as part of the project.
Green belt edge
Properties towards the green belt and in Forty Hill face tighter limits on extensions and outbuildings.
Approvals for house extensions in Enfield.
Many single-storey rear extensions are permitted development within the 3 or 4 metre limits, or 6 and 8 metres under prior approval. Conservation areas, flats, listed buildings and larger schemes need a householder application, and every extension needs building regulations approval.

House Extensions in Enfield: your questions.
Do I need planning permission for an extension in Enfield?
Not always. Permitted development covers many single-storey rear extensions on houses, but the London Borough of Enfield removes those rights in some conservation areas, and flats and listed buildings always need an application. We confirm the route at the site visit.
How long does an extension take to build?
Ten to sixteen weeks on site for a single-storey extension once approvals are in place, plus the design and approval period beforehand. Glazing has the longest lead time, so we order it early.
Which parts of Enfield do you cover?
